Reliability, Availability and Maintainability (RAM) Modelling Study of Gas Plant Design

Project goal

To help the client construct a gas plant that is designed to operate safely, efficiently, and effectively


Arran Energy


Natural Gas Plant Producer


Stanley liquids project in Papua New Guinea

The challenge

To determine what aspects of the design would impact the reliability, availability and maintainability of the equipment and processes on the plant, and how to mitigate these to help assure plant safety and productivity.

Why we were contracted

To assure the goals of the study were achieved, Arran Energy outsourced the project to Add Energy’s asset management specialists who were tasked with conducting a high-level qualitative assessment.

This provided an independent review, identifying risks and recommendations for design improvements ahead of Detailed Design, purchase of long lead equipment and construction.

What we did

  1. Review basis of design, relevant data, and available information.
  2. Analysis by modules in the form of block diagrams and process relationships.
  3. Identification of raw risks, and initial mitigations.
  4. Probability and consequence analysis of raw risks.
  5. Evaluation of priorities.
  6. Provide recommendations for design improvements.
